In-Place Activation Using Internet Explorer 5 Does Not Work for PowerPoint Slides

When you configure Internet Explorer to open Office files in the appropriate Office program on a computer that is running Windows NT 4.0, the in-place activation does not occur when you open PowerPoint slide files.

This behavior can occur because PowerPoint has two modes, Edit and Show, and you must specify one mode or the other in the registry for in-place activation to work correctly.

To resolve this behavior, edit the registry to use either the Edit or the Show mode when you open PowerPoint files with in-place activation.

NOTE: If you use Show mode, you can view the slides but cannot change them, and closing the slides returns you to Internet Explorer 5.

To configure Internet Explorer to open PowerPoint files in Show mode:
